DELETE STATEMENT





The “Delete” statement is used to delete records (all or selected) in a table.

Syntax:
DELETE FROM <Table name>
WHERE  SomeColumn=SomeValue

Note: Using where clause we can delete specific records. If we remove “Where” clause all records will be deleted.

Example:
Specific record deletion:
The table Sample_Table is having six records.


I want to delete a record which is having ID value 104.

SQL statement:
DELETE FROM Sample_Table
WHERE ID=104

Result: SELECT * FROM Sample_Table



The record (104) is deleted from the table.

Delete all records:
DELETE FROM Sample_Table

Result: SELECT * FROM Sample_Table



All records deleted.
